About this study

Official title: A Phase 1 First-in-Human Study of PTK7-Directed Antibody Drug Conjugate HWK-007 in Participants With Advanced Solid Tumors

HWK-007-101 is a multicenter, open-label, first-in-human (FIH) Phase 1 study evaluating HWK-007, a protein tyrosine kinase 7 (PTK7)-targeted antibody drug conjugate (ADC), in adult participants with advanced or metastatic solid tumors known to be expressing PTK7. The study employs a sequential dose escalation and dose expansion design without a control group.

Read the detailed description

The study consists of 2 phases, Phase 1a (dose escalation) and Phase 1b (dose expansion). In Phase 1a, participants with non-squamous Endothelial Growth Factor Receptor Wild type (EGFR Wt) NSCLC, platinum resistant ovarian cancer (PROC), and endometrial cancer will be enrolled. In Phase 1b, non-squamous EGFR Wt NSCLC expansion cohort(s) will be opened, based on the safety, tolerability, PK, and preliminary antitumor data in Phase 1a.

In Phase 1a of the study, HWK-007 will initially be administered as an intravenous (IV) infusion every 3 weeks (Q3W).

What is being measured

The primary outcome is the main question the study is designed to answer.

    Determine the highest dose of HWK-007 that can be administered without signs of toxicity measured at the end of Cycle 1 (21 day cycle) by: Incidence and severity of Adverse Events (AE). Incidence of Dose-Limiting Toxicities (DLT). Incidence of Serious Adverse Events (SAE).

    Measured: From Cycle 1, Day 1 until Cycle 1, Day 21 (21-day cycles)

  2. Determine Maximum Administered Dose (MAD)

    Determine the highest dose administered during the dose escalation part of the study measured at the end of Cycle 1 (21 day cycle) by: Incidence and severity of Adverse Events (AE). Incidence of Dose-Limiting Toxicities (DLT). Incidence of Serious Adverse Events (SAE).

    Measured: From Cycle 1, Day 1 to Cycle 1, Day 21 (21-day cycles) until the MTD is reached.

  3. Determine the Recommended Dose for Expansion (RDE)

    Determine the dose that will be recommended for further study within the tumor types studied in this clinical trial measured at the end of Cycle 1 (21 day cycle) by: Incidence and severity of Adverse Events (AE). Incidence of Dose-Limiting Toxicities (DLT). Incidence of Serious Adverse Events (SAE).

    Measured: From Cycle 1, Day 1 to Cycle 1, Day 21 (21-day cycles) until MTD is identified.

    Measured: Cycle 1 and Cycle 4 (21-day cycles)

  9. Clearance (CL)

    Measured rate at which HWK-007 is cleared from the blood following infusion.

    Measured: Cycle 1 and Cycle 4 (21-day cycles)

  10. Evaluate the Duration of Response (DoR) to HWK-007

    Measure the time from evidence of response by CT-scan until evidence of progression of cancer.

    Measured: From Cycle 1, Day 1 (21-day cycles) until disease progression or 24 months, whichever comes first.

  11. Evaluate Progression-free Survival (PFS)

    Measure the time from the first infusion of HWK-007 until evidence of cancer progression is detected.

    Measured: From Cycle 1, Day 1 (21-day cycles) infusion to End of Study (up to 24 months)

  12. Evaluate Disease control Rate (DCR)

    Measure the time from Cycle 1, Day 1 that cancer does not worsen by RECIST1.1 criteria.

    Measured: From Cycle 1, Day 1 (21-day cycles) until disease progression or 24 months, whichever comes first.

  13. Time to Response (TTR)

    Time from Cycle 1, Day 1 infusion of HWK-007 until evidence of response via CT scan according to RECIST1.1 criteria.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HWK-007 in people with Endometrial Cancer and Ovarian Cancer, run by Whitehawk Therapeutics, Inc. at 12 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 5 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Clinical Trial Manager Lead (866-742-9495, WHWK-Clinical-Trials@whitehawktx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Determine Maximum Tolerated Dose (MTD) (time frame: From Cycle 1, Day 1 until Cycle 1, Day 21 (21-day cycles)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Aug 2026.
